TIMEeSTAMP.

Specification of Letters Yatent.

Patented March 17, 1908.

Application filed April 24, 1903. Serial No. 154,057.

Be it Vknown that l, Fnnnnnioii PURDY, citizen ot the United States, residing at Chicago, .in the county of illinois, have invented a certain new and useful Improvement in Time-Stamps, of which the -following is a full, clear, concise, and exact description, reference being` had to the accompanying drawings, Aforming a part oi" this specification.

My invention relatesvto improvements in automatic time stamps..

It is among the objects of this invention. to provide a stan'iping device adapted to print time, in which proper contact oi' the impression device or mechanism with the surface being stamped will be insured without the use oi a platen, so that the size of the article which may be stamped thereby is unlimited, and which will be automatically inked.

Another object of the invention is to con-` struct an inking device in such a manner that it will not interfere with the movement of the means for varying the character of the impression adapted to be made by thestamp.`

There are various other objects oi the invention' which become apparent from the following description of one 'form of my invention which has been worked out for practical purposes` This Vforni of my invention is illustrated 'in the accompanying drawing, in which: k

Figure 1 is a central, longitudinal vertical sectional view of a hand stamp embodying the 'features ot my invention, Fig. 2 is a transverse vertical. sectional view taken upon line Q -2, Fig. l 5 Fig. 3 is a face view in de-A tail of the stamp; Fig. 4 is a like view oi my improved pad Fig. 5 is a view of an impression made b T the stamp shown in Fig. 3;

Fig. 6 is a perspective view in detail showing the stationary and movable pads and the manner of connecting the movable stamp with the latter; Fig. 7is a tace view oi' a modified form of inking p ad showing one por-v tion stationary and another revoluble; and, Fig. 8 is a 'face view ot a modilied iorin ot stamp mechanism in which a single dial is shown together with a cylinder having the characters A. M. and P. M., thereon, which cylinder is intended to be moved manually.

Referring to the drawings, therein is repre' base or frame a of any the gage parts a which being stamped, when an impression is being made, which frame is sented a supporting suitable form having Cook and State oi'" 1 provided with the vertical slots l), at the respective ends, through which pivot pins oi trunnions c, c, Fig. l, are projected into vertical end pieces d, d, which. are attached to or integral with a stamp supporting plate e. The trunnions c are connected with the branching arinf, rigidly attached to a handle y, having a hollow .tube therein fitted to telescope with a tube 71, attached to the horizontal portion or casing plate i of the frame, into which tube is inserted the spiral spring which serves -to lift the handle and thereby hold the stamp against'the hiking-p ad which is located beneath the plate i, as hereinafter described. The ends d constitute cams with curved'slots adapted to engage with studs lc upon the trame plates a, to cause the rotation of the stamp for the purpose of making the impression.

Inclosed within a casing l is a clock train in which fm. represents the spring inclosing barrel, n the minute arbor, 0 the hour arbor and p an arbor which rotates once in twentyfour hours. Mounted upon the ends of said arbors respectively, which projects through the plate c, are stamp disks q, r, s, respectively, which are adapted to rotate with said arbors. rlhe disk Q is provided with iigures representing minutes, the disk 1^ with characters representing hours, and the disk s with the characters A. M. and P. M., respectively, arranged diametrically opposite each other. Circular pads, t, u, o, respectively, of absorbent material, are pivot-ally attached to the plate i opposite to and coincident with said disk s or time stamp g, r, s, respectively, with which said pads are in contact when the stamp is in its norm al or inking position: Attachedto the plate e is a stamp w, upon which are placed characters representing the year, month and day of the week, as shown at w1, w2 and w3 respectively, Fig. 3 and upon which may also be placed suoli characters as may be desired. An ink pad Figs. 1, 2 and 4 is attached to the plate i, which pad has circular openings reception of the revoluble pads t, a, v.

formed therein for the Upon the stamp w, as shown in Fig. 3, are

is, of course, operated by depressing the handle which causes a half revolution of the stamping mechanism upon the pivots c, which causes the stamp to be brought into a printing position upon the surface provided to receive the impression, when, upon releasing the handle, the reverse action takes place caused by the spiing y', and the stamp is returned to its normal inking position. A winding stem is provided for winding the clock-train.

vWhile I prefer to employ revoluble pads in conjunction with the several time printing elements, it is not essential that more than the element which prints the minute should be provided with such a pad. I have, accordingly in Fig. 7 shown a construction in which but a single revoluble pad t is employed in conjunction with the stationary pad fc, saidpad t being located opposite the minute dial. Owing to the. fact that the other printing elements move so slowly and are so close to the source of power, the friction of the contact between them and a plain immovable pad isso slight that it need not be taken into account. It will be noted that the casing of the time stamp normally closes and shields the horologic motor and the impression means, thus protecting the same against dust, dirt and injury.

It is obvious that for the purpose of a time stamp it is not necessary that more than one of the time printing elements should be moved automatically, viz., that actuated by the hour-hand arbor. Such a construction is shown in Fig. S, in which i" represents the hour dial which is moved automatically, while s represents a cylinder having the characters A. M. and I). M. thereon. AThe aXis of said cylinder is at right angles to that of the dial 1" and it is provided with indentations s2, which enable it to be manually rotated by means of a pointed instrument. IYhile it is obvious that such a device might be used to advantage it is apparent that it lacks the nicety of precision of the preferred construction above described.

The device which I have designed'may be carried from place to place and impressions made therewith in rapid succession. The accuracy ot each impression is insured by the gage parts which guide the impression mechanism into proper engagement with the surface being stamped. By providing the gage parts instead of a platen to insure the accuracy of the impressions, the size oi' the article which may be stamped is unlimited.

As all the cooperating elements are contained in a unitary structure which is light and compact, this stamp may be readily moved from place to place for use, and since the impression mechanism is automatically inked, the impressions may be produced in rapid succession.

The pads herein shown are illustrative ot only one of the ways in which I contemplate inking the device. It is manifest that all of the parts of the device, which I have disclosed for the purpose of revealing my invention, are susceptible oi various modifications which will fall within the scope ot my invention and are intended to be within the purview oi the claims appended hereto.

Instead of varying the character of the impression adapted to be made by the impression mechanism by the stamp disks shown herein, I may employ type'wheels or other means, all of which I consider fall within the scope ot the broad claims of this application.

In an application tiled June 14, 1902, and renewed April 24, 1903, Serial No. 154,187, I have shown and described a form oftime stamp wherein the horologic motor is mounted stationarily upon the frame and the impression mechanism is movable therefrom in making an impression; the time stamp of the present 'application is one species embodying the general principle underlying the species in said application above mentioned and I have made said application the broad case and have inserted in addition to claims to the species therein disclosed, generic claims covering the species herein illustrated as well as the species disclosed in said above mentioned ap )lication and it will, therefore, be understood that the present application so tar as said generic claims are concerned is subsidiary to the application above mentioned.
